node-js-api-response-ts/src/asyncHandler.ts

Unified API response and error handling for Express.js in TypeScript. This package provides a middleware for consistent API responses and error handling in Express applications, making it easier to manage API responses and errors in a standardized way.

import { Request, Response, NextFunction } from 'express';

export const asyncHandler = (fn: (req: Request, res: Response, next: NextFunction) => Promise<any>) => {
    return (req: Request, res: Response, next: NextFunction) => {
        Promise.resolve(fn(req, res, next)).catch((err) => next(err));
    }
}
